Eaton P3BJDC3100GN DC Circuit Breaker - DC3100
Part Number: P3BJDC3100GN
Quick Summary
P3BJDC3100GN is a DC circuit breaker that protects critical DC power distribution in industrial automation. Too often, protection devices slow down maintenance when settings aren’t aligned with existing control architectures. Look for CE marking, IP-rated enclosure protection, and SIL readiness where applicable to ensure global compliance and safe operation. In practice, this device supports streamlined panel integration and predictable DC protection, delivering reliability, reduced downtime, and lower lifecycle costs for growing automation networks.
Product Information
DIN-rail mounting and plug-in design enable fast installation and straightforward panel modernization. The business impact is tangible: shorter commissioning times, fewer field wiring mistakes, and lower labor costs for upgrades. This approach is well-suited to factory automation DC buses and data-center power rails, where compact form factors and clean wiring simplify panel layouts and improve serviceability. Robust DC protection with predictable trip behavior reduces outage duration and arc exposure. By aligning trip curves with your DC bus design, engineers can minimize nuisance trips while preserving equipment protection. This is particularly valuable in robotics cells, servo drives, and other high-load DC circuits where uptime directly drives throughput and performance. Compatibility with Eaton’s P3B family and modular accessories provides scalability without changing protection strategies. This simplifies spare parts management and enables staged upgrades as loads evolve. Panel builders benefit from standardized interfaces and faster installation when expanding DC distribution across multiple lines or sites. Diagnostics and remote monitoring readiness give continuous visibility into device health and fault history. Integrated status indicators and compatible communication options support proactive maintenance and shorter mean time to repair. In continuous manufacturing environments, this translates into lower maintenance windows and fewer unexpected trips. Clear documentation, streamlined approvals, and consistent performance data support audit readiness and regulatory compliance. By standardizing DC protection across facilities, maintenance teams reduce variability and simplify supplier management. The result is safer, compliant, and more cost-effective power protection for industrial automation.
